I had a Coronary Artery Calcium scan (CAC scan) done in January of 2022. My score was bad, 563, indicating likely significant coronary artery disease. A few months ago, I tried the high dose Vitamin C (4,000 mg/day) and L-Lysine (4,000 mg/day) for four weeks. This therapy had been mentioned on GAW a few times in the past year or so. I had a follow-up CAC scan done on Tuesday, my new score is 698. I'm not too happy. This therapy may have worked for some people, but seems pretty clear it didn't work for me. I also did a round of a lemon juice/garlic elixer earlier in the year. If anyone else has tried the Vit C-Lysine therapy and have results to report, please post here. Thank you. (now I need to figure out what to do with a few bottles of Vitamin C and Lysine; I had planned on doing more rounds of the "therapy" if it had shown ANY positive results. I guess it could be argued "well, just think how high it would have been if you didn't do that therapy!" :) )

This made me curious so I started searching on different types of plaque that cause blockages and what is lysine effective on. There are differences and I was not aware of this. Still, the limited published research on this topic indicates lysine and vitamin C are effective. Calcified plaques are Made up of mostly calcium and Less likely to cause a plaque rupture or heart attack. Lysine is primarily thought to be beneficial for reducing plaque buildup related to lipoprotein(a) (Lp(a)) in the arteries. There are articles the say it's helpful for calcified plaques. I would continue to take it if I was in your position. There's enough info to support taking it. I have been for almost a year now and it's an easy and inexpensive thing to do. It may help you in the long-term. I hope this gets better for you.
Perhaps I'll up my daily vitamin C, and add lysine. I only took supplemental lysine during the regimen. Thanks for your input.
